Generational change through time can be observed, as every generation of every species is slightly different than its parent generations. What you call macro evolution (specieation) does not occur in one generation, so the ToE would not predict such an outcome.<quoted text>
You can call the single-generation demand ridiculous, but stating that macroevolution has been observed in the fossil record without it is incorrect since evolution defines itself as generational change thru time. To observe macroevolution in the fossil record requres observing, between endpoints, a full set of changes each step of which could be accomplished in one generation.
Another continuum is a calendar. Though it does not show us minute by minute advancement, it does show us day by day advancement. Kind of like evolution shows us a continuum in the fossil record.
